A basic rule of interpreting documents is that you need to read it in a way that reconciles all parts which address the same subject, and not ignore the portions you find inconvenient.
And that is exactly my point regarding your incomplete reciting of the 4th paragraph of the 3rd bulleted section and how the full and complete reading of such actually does not declare accuracy of feature location as a determining factor.
I recommend anyone curious on this subject to ready the 4th and 5th paragraphs of the 3rd bulleted item carefully and fully and, as Mr. Page states, along with the entire letter contents.
They reconcile well, in my humble opinion.
